Plea

Answer 1

Remember, a function with a 0 at a + bi must have a 0 at a - bi. With those, you can build the factors then multiply them out.

Answer 2

Answer 3

you get this polynomial function than you multiple (x -4)(x+8)(x-(2+3i) so than you can writing that f(x) = (x-4)(x+8)(x-(2+3i))

these you can writing because 4 and -8 and 2+3i are given roots of this polynomial

hope helped

Answer 4

@iwanttogotostanford
Yes, your answer is correct.

Answer 5

@jhonyy9 you forgot that if 2+3i is a root then 2-3i is also a root.

Answer 6

oh yes - sure thank you
